DUMP BODY FOR TRUCKS.

Application led February 27, 1925. Serial No. 11,990.

To all whom t may concern.'

Be it known that I, RAY J. WINGER, citizen of the United States ofAmerica, residing at Brush, the county of Morgan, and State of Colorado,have invented certain new and useful Improvements in Dump Bodies forTrucks; and I do declare the following to be a full, clear, and eXactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the characters of reference markedthereon, which form a part of this application.

This invention relates to improvements in the construction of dumpbodies for trucks. In the transportation of materials of various kinds,a large amount of time and labor can be saved if the load can be readilydumped as the labor of unloading canI thereby be reduced to a minimum.

I am, of course, aware that many different means for operating dump]bodies have been invented, many of which are in use today. I have,however, invented a specifically different dump body than any that is atpresent known to me. The ob] ect of my invention is to produce a dumpbody that shall be adapted more particularly to horse drawn trucks andwhich shall be so constructed that the power required for hoisting anddumping shall be supplied by the team.

The above and other objects that will become apparent as the descriptionproceeds are attained by means of a construction that I will now proceedto describe in detail, reference for this purpose being had to theaccompanying drawing in which the present preferred embodiment of theinvention is shown and in which v Fig. 1 is a side elevation of myimproved dump body, showing the same in place on a truck.

Fig. 2 is a section taken on line 2-27 Fig. 1.

Fig. 3 is a section taken on line 3-3'. Fig. 1.

Fig. 4 is a side elevation showing the body in dumping position.

Fig. 5 is an end view, with 1warts broken away and parts shownV insection, said view being taken along line 5-5, Fig. 4 and shows the dumpbody in tilted position as it appears bef-ore the body has been hoisted.

Fig. 6 is similar to Fig. 5 and shows the body both hoisted and tilted.-

Fig. 7 is a view taken along line 7-7, Fig. 5 and shows the manner inwhich the cables are resiliently attached to one of the side members andFig. 8 is a detail showing the double drum to which the ends of eachpair of hoisting cables are attached.

The truck that I have shown has merely been indicated for the purpose ofbetter illustrating my invention and is n0 part of the invention. Thetruck has a pair of front wheels 1, a pair of rear wheels 2, reach 3 andholsters 47 in the usual manner. Transverse timbers 5 rest on the uppersurface of the holsters 4 and are secured to the latter by means ofclamping rods 6. To the upper side of the transverse members 5, I securetwo parallel spaced beams to the upper side of which I secure a numberof transverse frame members 8, that are secured to the beams 7 by meansof bolts 9, or other suitable means, and I preferably provide fourtransverse frame members 8. To the ends of members 8- I attach hooks1()` whose function and mode of operation will hereinafter appear. Atthe rear and front of the side beam 7 I secure vertical standards 11that are held in place by bolts 12 that pass transversely through theframe in the manner shown in Figs. 5 and 6. These uprights are braced bymeans of diagonal braces 13 and have attached totheir tops castings 14(Fig. 3) each of which carries two pulleys 15 over which the cables 16run. A shaft 17 extends lengthwise of the frame and is journalled in thetransverse pieces 18. Near each end of shaft 17 I secure spaced collars19 (Fig. 8) which form spools on which the cables 16 may be wound in themanner shown most clearly in Fig. 8. A drum 20 is secured to the shaft17 about midway between its ends. A cable 21 is wound onto the drum 20and has one end attached to it. The other end of this cable carries oneor more links to which a whiiiietree may be attached. A team of horsesmay be attached to the whiflletree for the purpose of rotating the shaftand for winding the cables 16 thereonto. The box or body in which theload is carried consists of a plurality of transverse members 22 whoseends are connected by means of longitudinal beams 23. A plurality ofscantlings or two by fours 24 are secured in parallel relation totheupper surface of the transverse members 22 and to the upper side ofthese the floor 25 is cured. Ends 26 are secured to the front and rearof the bottom and these cooperate with the sides 27 to form a box. Thesides are hinged so as torotate about the axes of the rods 28. Rods 29are secured to the lower side of the transverse members 22 and are sospaced that they rest in the hooks 10 in the manner shown in Fig. 2.lVhen the box is tilted it rotates about one of the rods 29 until it isin position to be hoisted.

By referring more particularly to Figs. 4 to 8, we will see how thedevice operates. The cables 16 shown to the right in Figs. 5 and G passthrough suitable openings in the beam 23 and are anchored to the latter.The cables on the left, however, are about two feet longer than those onthe right and pass through holes in member 23, thence around pulleys 30through notches or openings in the brackets 31 and are joined to thefree ends of the springs 32 whose other ends are anchored to brackets 33in the manner shown most clearly in Fig. 7. Secured to the end of eachcable 16 adjacent its connection to the spring 32, is an enlargement orball 34 that engages the bracket 31 and forms a stop which limits themovement of the cable. The ends of the beams 23 project over theuprights 11 and are provided with pulleys 35 that engage in andcooperate with the guide grooves 36. The tension of springs 32v issufficient to prevent any slack from forming in the cables to which theyare attached.

Let' us now assume that the parts are in the position shown in 2 andthat a force is applied to the cable 21 which is sufficient to rotatethe shaft 17. The cables 16 will be wound onto this shaft in the m'annerobvious from the drawing. The right hand side of the box will be raisedin the manner shown in Fig. 5. The cables that are attached to the lefthand beam 23 will slide through the same until the member 34 engages thebracket 31 when the relative movement will cease and both sides willthereafter be hoisted at the same rate until the parts assume theposition shown in Fig. 6. The amount of inclination of the bottom may beas great as necessary to effect complete dumping of the particularmaterial handled.

I want to call particular' attention to the construction which permitsthe box to be first tilted and then hoisted to the extent necessary. Itis not always necessary to raise the box as the unloading may,obviously, take place by merely tilting the box, but it may be necessaryat times to hoist it also. The idea of having the cables on one side soconnected that they will slide for some distance gives a simplemechanism for tilting which I believe to be new.

Having now described my invention, what I claim as new is:

1. In a dump body construction, in combination, a. supporting frame,vertical standards at each end thereof, a body supported by the frameand located between said standards and means for hoisting the oppositesides of said body to different heights, said means comprising a cablefor each corner of the body, the cables attached to one side having alost motion connection with the body whereby they will not becomeeffective for the purpose of raising the body until the other side hasbeen raised to some distance.

2. In a dump body construction, in combination, a supporting frame,vertical standards at each end thereof, a body supported by the frameand located between said standards and means for hoisting opposite sidesof said body to different heights, said means comprising hoisting drumssecured to the frame beneath the body, cables having one end connectedto a drum and the other end connected to opposite sides of said body,the cables that are connected to one side of the body having a lostmotion connection 90 with the body and the cables connected to the otherside being positively connected to the body whereby when the hoistingdrums are operated the body will be tilted before it is hoisted.

3. In a dump body construction, in combination, a frame having verticalstandards near each end, a body member adapted to be supported on saidframe between said standards, a shaft rotatably connected to the frameand extending lengthwise thereof, said shaft having hoisting drums neareach end, said drums being each located underneath in the plane of onepair of said standards, pulleys secured to the standards near the topsthereof, cables having one of their ends attached to said drums and theother ends being connected to the body, one cable near each corner ofthe body, the twocables on the side to which the load is to be vdumpedhaving a lost motion connection with the body and means for rotating thehoisting drums.

4. In a dump body construction, in combination, a frame having verticalstandards nea-r each end, a body member adapted to be supported on saidframe between said standards, a shaft rotatably connected to the frameand extending lengthwise thereof, said shaft having hoisting drums neareach end, said drums being each located underneath in the plane of onepair of said standards, pulleys secured to the standards near the topsthereof, cables having one of their ends attached to said drums and theother ends being connected to the body, one cable near each corner ofthe body, the two cables on the side to which the load is to be dumpedhaving a lost motion connection with the body and means for rot-atingthe hoisting drums, said means comprising a drum secured to the shaftintermediatethe hoisting drums.

5. In a dump body construction, in combination, a fra-me having Verticalstandards near each end, a body member adapted to be supported on saidframe between said standards7 a shaft rotatably connected to the frameand extending lengthwise thereof, said shaft having hoisting drums neareach end, said drums being eaeh located underneath in the plane of onepair of said standards, pulleys secured to the standards near the topsthereof, cables having one of their ends attached to said drums and theothers ends being connected to the body, one cable near each corner ofthe body, the two cables on the side to which the load is to be dumpedhaving a resilient lost motion conneetion with the body and means forrotating the hoisting drums.

In testimony whereof I alix my signature.
